To investigate the infiltration capacity under different land use types in typical Bashang region (wind erosion area) and Baxia region (water erosion area) in Zhangjiakou city, Hebei province of China, a Mini Disk Infiltrometer was used to measure soil infiltration capacity of different typical and representative land use types (i.e., cultivated land, forest land and grassland) in Yangyuan and Zhangbei counties. Meanwhile, the influencing factors of soil infiltration capacity were analyzed. Different soil infiltration capacities were found among different land use types. In Yangyuan county, the soil infiltration capacity of the high coverage grassland was the highest among different land use types, and the soil infiltration capacity of the low coverage grassland was higher than that of the cultivated land and forest land. Meanwhile, the soil infiltration capacity of forest land was the lowest among different land use types in Yangyuan county. In Zhangbei county, the soil infiltration capacity of the grassland was the highest among different land use types, and the soil infiltration capacity of the cultivated land was higher than that of the shrub land and shelterbelt land. Meanwhile, the soil infiltration capacity of shelterbelt land was the lowest among different land use types in Zhangbei county. A significant difference in fitting degree could be found among infiltration models. Philip model had the best fitting degree. This result indicated that Philip model should be applied to simulate soil infiltration process of Zhangjiakou city. A significantly negative correlation could be found between bulk density and soil initial infiltration rate, as well as stable infiltration rate and stable infiltration time, while a significantly positive correlation could be found between the total porosity and soil initial infiltration rate, as well as the stable infiltration rate and the stable infiltration time. The results indicated that the grassland had the highest soil infiltration capacity among different land use types and more attention should be paid to the role of grassland in the ecological engineering project so as to enhance the ability of soil water conservation in this region in the future.
